Letters .Patent No. 64.074, sluier? April 23, 1867` MPROVED WINDUW-SASH FRAME. I

TO ALL WHOM IT MAY CONCERN:

Be it known that I, EDWIN CLARK, ot' the city and county of Lancaster, in the State of Pennsylvanie, have made a new and useful improvement in Window-Sashes and Frames; and I do hereby declare tho following to be a fnll and exact description of the saine, reference being had to the accompanying drawings, making part of this specification, and-in which A Figure 1 is a vertical'scction of a window-frame and sashes, showing my improvement.

Figure 2 is a vertical section, showing the manner of attaching the strip which holds the sash in place.

Figure is a detached sectional view of the manner of attaching the sash to the sliding strip.

Figure el is a 'transverse horizontal sect-ion through the left side of' the window-frame; and

Figure 5 is a detached sectional view, showing thc manner of'attaching theweighted rope to the sash,

Similailetters of reference indicate corresionding parts in the several gures. l i

The nature of in v invention consists in providing novel means to take the window-'Sashes out from the frame, so as to prevent the necessity of standing on the window-sill on the outside of the upper` stories of buildings, which is now the common practice of servants when washing the windows, or of painters when re-painting sashes.

To enablc'others skilled in the art to which my invention npp'ertains to fully understand and use theV same, I will now proceed to describe its construction and operation.

A, in my drawings, may represent the frame of a window, and B the upper, and BI `the lower sash of the same. The left upright piece of the lower sash Bl is constructed of two pieces, 11 and l, the piecetl of the sashbeing provided with :1 groove, c, sliding over an inclined tongue, d, on the piece b. The widest part of this tongue is at its top, and is provided with a. hoch-shaped projection, (Z1, which catches under a. slot, cl, in the4 groove c of thc piece b'. At the lower end of the tongue d is fastened a straight spring, ci, which catches under the eye c2 in the groove 1.-. When the piece 11 is slid on thel piece b, the projection al.1 glides into the slot el, the

veye c2 o'vcr the spring cl2, and the inclined face of the tongue forces the two pieces b and bl closely together.

Rutas the wood in the sash is likely to shrink or expand with the changes in the weather, which wouldl either allow the window to rattle or tighten the tongue so in the groove that it would be diicult to separate there, I.

prefer the use of two springs on'astraight tongue, which, if the wood shrinks, will draw the two pieces together and hold them irmly to each other, or, as the wood expands, will gradually give with the wood, so that the sash-frame will always be perfectly air-tight, and the two pieces 6 and bl can still bc separated with perfect ease.lv In the upper part ot' the outer edge of the piece Z1, as well as on the corresponding part of the other upright of thejlower sash, and the corresponding parts of the upper sash, are formed grooves, e, to hold the weighted ropcsf, by means of which the sashes are raised and lowered. These grooves terminate in a groove, el, running upwardly, which catches and securely holds the knots of the ropef. I am aware that grooves have` been used for this purpose, provided at their lower ends with a hollow place for the knotto lie in, out of the way of the sliding of the sash, but in these cases the employment of metal plates isnecessary to hold the rope in place,

`vhilst by means of my peculiar shaped groove, c el, I am enabled to dispense withany other fastening for the ropes, and to readily attach the sash to the ropes or detach it from them, The sashes are held in place by and slide between the inner strip g, the centre strip 71., and the projecting part et' the frame-A. 'Ihe strip L is removable, fitting in a .groove in the frame A. The strip g is also similarly'removable, and is provided with three eyes, g, through which pins, j, pass from the inner side of the fratrie far enough to pass inte holes in the' strips h in such x1 manner that the pins j hold both strips at once. Though it is not necessary, still I prefer to make the strip ,o with a tongue, g, fitting into :i corresponding 4groovelin th'cgroove into which the strip g lits',

and to which tongl1e,//', the eyes ,r/l are secured. .ily this arrangement I gain additional security against the shaking loose of the strip Il/ when the window is shaken by the wind and storni, and prevent the rattling of the same. I provide the pins with fancy heads, so that they slm-ll be an ornament to the frame.

Operation.

To remove the lower sash alone, l place a pin, which for that purpose muy always be kept in a separate hole in the frame A, into the hole k, which passes through the strip .r/ into but not through the piece b. This pin holds the latter firmly in place, whilst by raising the sash the same will be separated freni it, the slet e* sliding from the projection "Z1, the eye ci from the spring riz, and the groove r: from the tongue d. As seen as the groove yc is .clear from the tongue cl, that side of the sash can be swung out, which will enable the other side Ato be removed Vfrom its groove. The rope can be detached by simply taking it out of the groove e c, and may be fastened to a-pin placed Ain the frame for that purpose, or may be allowed to run up to the roller, where it will he held by the knot, and the .sash is detached from the frame and can be taken anywhere to be cleaned or painted. To take out the upper sash,y I withdraw' the pin holding the piece b from the hole c, which allows the same to be taken ott the rope, and take out the three pins j, thus at once freeing both strips g and h, which, when removed from the grooves inthe frame in which they are held, leave one side of the sash clear from the frame .and easy to be taken out, when the ropes are detached and the sash can be taken away. To replace the:

sashes, I rst attach the ropes of the upper sash by simply placing them in the grooves e, the knots resting in the parts el. I then replace the `sash in its proper position and replace the strip 7L. I thon attach the piece b to the part `b1 vof the lower sash by sliding the groove c over the tongue d, the slot cl slipping over the projection d1, and the `eye c2 over the spring (Z2, replace the ropes in the grooves and the sash into its place, when by returning the strip y `into the corresponding groove in the frame A, and pushing the pins j through the same and the eyes gl into the strip 7L, the whole is again securely fastened. To simply remove and replace the lower sash, I need not remove either the pins j or the strips g and L. I remove .it as described above, and in replacing it merely place 'the solid upright of the sash into its correspondinggroovein the frame A, and the groove c over thetongue CZ, when by vpushing the sash down it fastens itself` to piece b, as described. Byv removing the pin from the hole k the sash .is again free to be oper-ated, the weight of the sash, combined with the action of the inclined face of the tongue d, the projection dl, and the slot cl, and the spring d2 and eye c2, keeping the pieces b and bl firmly attached to each other.

I am aware that it is not new to make one or both of the upright pieces of a sash in two parts, they having been so constructed that the two pieces .are held'together byvmeans of a catch on the inside ofthe sash, which,` when accidentally broken or loosened, 4would permit the sash to fall from its place,there being nothing to prei vent its coming ontJ laterally in case of such an accident. But by my invention I can not only as easily detach the sash, but when not detached keep it in place as strongly and securely as any sash the uprights of' which are made undivided. i

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is1

l. vThe inclined tongue Z and corresponding groove e on the pieces and bl, respectively, of a window-sash, substantially as and for the purposes described. p

2. The projection all on the inclined tongue c?, slots nl, springs C12, and eyes c, on the pieces 6 and b1, respectively, of a window-sash, substantially as and for the purposes described.

3. The eyes gl on the stripsg and pins j, passing through the same and the window-frame, substantially as described.

4. The tongueg2 on the strip g, and corresponding groove in the frameA, substantially as and for the purposes specified.

5. The above-described mode of removing and replacing window-sashes from frames, substantially as and' for the purposes specied.
